<P>PROBLEM TO BE SOLVED: To provide a control device of lock-up clutch for vehicle performing learning control high in accuracy with respect to pressure difference defining engaging condition. <P>SOLUTION: Since, in a steady traveling state, the pressure difference ΔP is gradually decreased from a point where the lock-up clutch 26 is engaged, and a learning control with respect to a pressure difference ΔP at a point at which the lock-up clutch 26 begins to slide is performed, the pressure difference ΔP in a transition period from a static friction condition of the lock-up clutch 26 to dynamic friction condition can be learned accurately, and the limit lock-up clutch capacity in the static friction condition can be defined suitably. Therefore, an electronic control unit 50 of the lock-up clutch for vehicle performing the learning control accurately with respect to the pressure difference ΔP defining the engaging condition can be provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
